In the Second Canadian Border War in 2020, the Montana National Guard teamed up with NW Shipping Co. to use armored trains to protect its shipping from Canadian raiders. The Lucky Strike was one of the last commissioned in her class, and one of the most successful.

About this creation

As you can see, the Lucky Strike is well suited to its environment...
Supply car, with a large bit of flexibility it defends the rear area of the train from aircraft and raiders.
In this configuration, the LS itself is a raider, probably sent ahead of one of its sisters to clear the tracks.
The head of this beast, the Lucky Strike itself is armed to the teeth with one 75mm howitzer, one 45mm cannon, and one 12.7mm machine gun.
Firing HE and AP rounds from a smooth bore, the LS can clear many different types of obstacles that threaten its progress.
Weighing in at 400 tons and rated at 20,000 hp, this is the largest and most powerful one produced.
Just showing off some details. Frag shields, pindle mounts, things like that.

The periscope lets the conductor see everywhere whilst remaining in complete safety.
Here's how I did the angling of the window pieces, if you didn't guess already.
Just a quick fix with the 1x2-1x1 converter.

What's funny, is that most of the train yards around Buffalo and Niagara are not in full use, so I don't think too many would attack there

That's why this is in Montana...

Now I'm no expert, but there isn't that much snow along the 49th. Anyway, nice build, and I think I may have to make the Canadian side if this. You know, with our "armed" "forces".

Yeah, and I'm not too sure how many tall mountains there are there in that region. Call it poetic license.
